Kat Von D -- Creepy Fan Hit with Restraining Order

EXCLUSIVE

Kat Von D can breathe a sigh of relief -- at least for the next three years -- because she's been granted a long term restraining order against the obsessed fan who was harassing her nonstop.

As we previously reported, Kat claimed a man named Michael Nunn sent her creepy messages on Twitter ... showed up to her house uninvited ... called her phone constantly ... and creeped up on her at public events.

She already had a temporary restraining order in place against the guy ... who she claimed exhibited "delusional and paranoid tendencies, including the belief that the FBI is watching him."

Now, the judge has ruled ... Nunn's restraining order should be extended until 2015 -- which means he needs to stay at least 300 yards away from Kat at all times ... and that includes internet contact.
